| 摘 要： | 信度与效度是衡量心理测验质量的重要指标。增加测验长度是提高测验信度和效度的重要方法之一。由于各学者对效度的代表符号规定不一，导致对于说明测验长度与测验效度关系的公式及其计算结果难于理解和解释。根据经典测量理论对代表测验长度与测验效度关系的公式进行分析和讨论，提出测验效度与长度关系的表达公式。

| Abstract: | Increasing the length is one of the best ways to improve validity and reliability two of the most important criteria in evaluating psychological tests. It is difficult to understand the formula illustrating the relationship between reliability and validity and its calculating result due to the diversity of symbols used by different scholars to represent validity. An analysis of formulas is made based on classical testing theories and a new formula is put forward to explain the relationship between test validity and test length. |
